FLOW CONTROL ADJUSTMENT
Open and Close: The material flow is shut off by moving
Control Lever to the left and locking into "V" notch on
calibration plate.
Flow Setting: To set the flow rate, put the Control Lever in
the shut-off position (in "V" notch). Determine your required
number setting as described below. Loosen the nylon wing
nut and slide to the desired number setting and retighten the
wing nut. Release the control strap and it will open to the
pre-set position.

NOTE: Fertilizer application rates as described are affected
by humidity and the moisture content of the material;
therefore, minor setting adjustments may be necessary to
compensate for these conditions.

ALTERNATIVE FLOW CONTROL SETTING
To determine the required setting for materials not listed on
chart, proceed as follows:
Determine from material bag, the amount of material to be
spread over a designated area. Example: "The contents of
this bag (25 lbs.) will cover 5000 square feet."
Determine the amount of material required to cover 100
square feet as follows:
-Add two zeros to bag weight. Example: 2500
-Divide this number by the number of square feet
on the bag.Example: 2500 divided by 5000 = .5
pounds of material for 100 square feet. NOTE: To
convert this weight to ounces, simply multiply by 16
(16 oz./lb) Example: .5 lb. x 16 = 8 oz.
Determine approximate Flow Control Setting by using chart
below showing type of material to spread.
Measure off a distance of 40 feet in your yard. This is the
distance your 30" spreader must travel in order to cover 100
square feet.(2.5 ft. (30") x 40 ft. = 100 sq ft.) For 40"
spreader measure off a distnce of 30 feet in your yard, the
distance to cover 100 square feet.
(3.33 ft. (40") x 30 ft. = 100 sq ft.)
Set the spreader flow control at the approximate flow control
setting.
Place 5 pounds of material in the Hopper. Weigh the
material before and after spreading 100 square feet to
determine amount of material used.
Move unit to measure area, lower aerator tines, open Flow
Control Lever. Drive the 40 ft. course, stop unit and close
Flow Control Lever.
Remove and weigh remaining material. Subtract this weight
from 5 pounds to determine material used: If too much
material is used: Set Flow Control ONE number LOWER
and try again. If too little material is used: Set Flow Control
ONE number HIGHER and try again.
After determining proper setting always record the type of
material and the setting for future use.

MAINTENANCE:
Should rust appear on any other part of your Aerator-
Spreader, sand lightly to remove rust and coat lightly with
enamel.
Apply a drop of lubricating oil to each nylon bearing (aerator
tine shaft, agitator shaft, and wheels) before each use.
Be sure to remove all unused fertilizers from hopper
immediately after use and clean with water.
To prevent rust in aerator tines, apply a light coat of oil on
the working areas of tines after each use.
After each use, service unit as described and store in a dry
area, shielding tines to avoid injury.
